School organization is the structure within which school administrators, supervisors, teachers, and pupils carry out the activities of the school. It includes both informal and formal organization, the latter capable of being represented in organization charts that show lines of authority and responsibility. School organization involves a planning process, the determination and assignment of duties, and a method of integrating and coordinating efforts of all individuals concerned with education. In a school system that is well organized, the administrator is in a better position (1) to delegate responsibilities, (2) to indicate what tasks and responsibilities are assigned to each individual, (3) to stimulate, coordinate, and unify efforts and energies within the system, and (4) to marshal the resources available in order to realize the objectives of the system. The details of constructing an organization chart are presented along with sample charts and discussion for large and small school systems. (TT)
